Zinc can stop cold viruses from copying themselves and spreading in lab tests.
Taking zinc gluconate lozenges when you have a cold might help you get better about 7 days faster than if you didn't take them, according to a study.
In studies where people tried zinc gluconate lozenges, most just noticed a bad taste or some mouth irritation, but nothing serious happened.
Taking zinc lozenges every few hours might help people get over a cold faster, with more people feeling better in a week compared to those who don't take them.
